my instincts are that while this problem might exist, you would only actually run into it if using a language specifically designed to create this problem.
I think it’s actually worse. If I understand correctly, corollary 14 implies that for any choice of the programming language, there exist some mixtures of environments which exhibit that problem. This means that if the environment is chosen adversarially, even by a computable adversary, AIXI is screwed.

Hmm, well you can’t choose the laws of physics adversarially, so I think this would only be a problem in a pure virtual environment.
The laws of physics may allow for adversaries that try to manipulate you.
